(EN-RSL-HW) Standard deviation 2052700100012
The mean neutron energy and its standard deviation 2052700100013
were estimated as 14.7 +- 0.2 MeV, when allowance is 2052700100014
made for the variation of neutron energy as a function2052700100015
of angle to the beam, and of the decrease in energy of2052700100016
the beam as it penetrates the target. 2052700100017
SAMPLE Nickel oxide, 0.7800+-0.0003 g. of Ni/g. of Ni-O, 2052700100018
in a Ni-O/Fe mixture irradiated in a cylindrical 2052700100019
polyethylene container. 2052700100020
METHOD (ACTIV) 2052700100021
After irradiation of NiO/Fe mixture, rapid clean 2052700100022
separation was performed by electromagnet. 2052700100023
DETECTOR (NAICR) 76 * 76 mm NaI crystal. 2052700100024
